ELEVATOR-CONTROL ATTACHMENT FOR rrrnsn'rrrncmeeninns.

Application fil ed October 12, 1926. SerialNo. 141,256.

'riage has returned to its regular position;

' second, to provide an attachment of this class which will relieve the operatorfrom con tinually watching delivery carriage. before raising the assembly elevator before setting another line; third, to provide an attachment ofthis class which will reduce to a minimum the mashing or breaking of the line delivery carriage while it is returning to itsnormalseating posi-' tion, which happens when the assembly elevator is raised too soon or before the carriage locks; fourth, to providean attachment of this class which reduces the opera'tors responsibility in operating the linotype or type setting machine; fifth, to rrovide an attachment of this class which facilitates the operation of the type setting machine, particularly when the operator is setting short measure, the elevator is often] raised too quickly before thel-ine delivery carriage re-,

provide an attachment of this class which in operation does not in any way affect the nor- 1113.1 operation of themachine except to facilitate its operation; seventh, to. provide an attachmentof this class which is applicable for the diflierent'types of type setting machines now in use without changing-the construction thereof; eighth, to provide an attachmentof this class which is so constructed if necessary before it reaches the first elevator position, and ninth, to providean attachment of this class which is very simple and economical of construction, durable, easy "to operate, efficient inits action, and which will not readily deteriorate or get out 'of order.

lVith these and other for the return of the line.

I turns, causing breakage of parts; sixth, to

that it will permit the return'of the'elevatorf objects inview, as

will appear hereinafter, my invention con- SIStS of certain novelfeatures of construction,

combination and arrangement of parts and portions as will be hereinafter described in detail and particularly set forth in the appended claims, reference being had to the accompanying drawings and to the characters of reference thereon, which forma part of this application, in which Figure 1 is a front elevational view :of a

type setting machine (in this case 'I' have shown a fragmentary view of a lin'ot'ype 'niachine) showinginy attachment in operative position thereon; Fig. 2 is a sectional view of .the machine and attachment'through' 2-2 of Fig. 1, and showing the attachment by dotted lines, positioned to lock the ele va'tor down,1and Fig. 3 is a sectional view. through 33 of Fig. 1. i I Similar characters of reference refer to similar parts and portions, throughout the several viewscof the drawings. I

The support '1, bolt 2, lever 8, roller 4, and cam member 5 constitute the principal parts and portions of my attachment. 7

The support l is rigidlysecured to the as seinbly elevator support base plate A of the assembling elevator of the type setting machine byineans of screws 1% through a flat lines in Fig. 2 of the drawings.

It will be' here noted that the lever'3 as sumes this dotted line position by gravity be cause of its-offset mounting. The upper end of the lever 3 and 8 is curved as best shown j in Fig. 2 of the drawings, so that'it extends around the reinforced portion of the elevator slide bar A, shown bestin Fig. Qof'ithe drawings. Mounted uponthe upper end. of the portion 3 is a roller member 4, which is adapted to revolve thereon. Above this roll end. is the delivery slide barIC of the co'nven plate on the front upper portion ofsaid-sup-v andspring at the position of the lever portional typesetting machine. Secured on the back face thereof, and extending below the same and adapted to engage the roller .4 is a cam member of suflicient length which is provided with a cam face on one side, so that when the slide bar C reciprocates back I wardly and forwardly, it engages the roller 4 and shifts the lever 3 to the posit on shown by solid lines in'Fig. 2 of the drawings,-

whereuponthe elevator can be raised. This, however, only happens when the elevator is in its returned position so that the cam 5 engages the roller 4. When'the slide bar Vmoves forwardly, the lever assumes the osi tion shown by dotted lines in F 2 o. the drawingsby gravity and prevents the movement of the elevator upwardly.

It will be notedthat the back side of the portion 3 engages the inner side of the horizontal cross portion 1 of the support 1 and serves as a stop when the lever 3 is in the position shown by dotted lines in Fig. 2 of the drawings, thus preventing the lever from droppingback too far so that itwill not engage the cam '5 with the'reciprocation motion of the bar C. f

It will be noted that the portion B is followed out at B and provided with a spring B adapted to operate the hook member D. The lever portion 3 tends to engage this hollowed out portion B andv wear on the same.

In order to obviate this I have provided, a

plate 6 adapted to cover the hollow portion the delivery carriage moves a certain distance,

i it releases a hook allowing the assembly elevator to drop to its seating position ready for the operator to set another line, but before he cando so he must be sure and wait until the line of the delivery carriage has come back to its regular position bythe cam action back of the machine before he raises the elevator A r again, all of which is the conventional manner of operation; With the attachment, hereinbefore described, when the assembling elevatorv is raised and the delivery carriage,

moves forwardly in a lateral direction, it

releases the lever 3 on, the face plate of the elevator, which slides against the back of theassembly elevator and as soon as the assembly elevator drops into its seating or assembly v position, the lever 3 falls withinthe top back of. the assembly box a slight distance, but not enoughto interfere with the assembling ofthe its normal position. WVhen the assembling 'ters Patent is:

next line of matrices, thus preventing the assembly elevator from belng raised until the line of the delivery carriage is'returned to elevator is in place andthe line of delivery carriage is in its normal position, the lever is in a neutral position, thus allowing the elevator to be moved upwardly, but when the line of delivery carriagemoves the line of mats over toward the first elevator, the assembly elevator cannot be moved upwardly until the carriage comes back; p t

It will be noted that the attachment,- as shown and disclosed herein, is in connection with the conventional linotype type setting machine, but it is applicable for the different makes of type setting machines now inuse, and although I have shown anddescribed a particular construction, combination and arrangement of parts'and portions, I do not.

wish to be limited to this particular construction, combination and arrangement, but desire to include in the scope of my lnvention the construction, combination and arrangement substantially as set forth in the appended claims. 7

' Having thus described my invention, what I claim as new anddesire to secure Let- 1. In a type setting machine having an assembly elevator and a delivery slide bar, a support rigidly secured tothe base plate of" the support for the'assembly elevator of a type setting machine, a gravity actuated lever pivotally mounted'on said support adapted to engage said elevator, stop means on, said support for regulating the movement of said lever, a cam member secured on the delivery slide bar of the type setting-machine adapted to engage one end of said lever for-shifting its opposite end out of engagement with the elevator. p r

; 2. In a type setting machine having an assembly elevator and a delivery slide bar, a support rigidly secured to the base plate of the support for the assembly elevator :of a type setting machine, and a gravity actuated lever pivotally mounted on said support adapted to engage said elevator, means for regulating the movement of said lever, a cam member secured on the delivery slide bar of the type setting machine adapted to engage 'oneend of said lever for shifting its opposite end out of engagement with the elevator, and a roller positioned on said leveradapted to engage said cam member; v

3.'In a typesetting machine, a supportse cured to the front upper portion of the as sembly elevator support base plate, said supporthaving a rearwardly extending bridge portion, a' lever pivotally mounted within said bridge portion, saidlever provided with a downwardly extending'curved portion, the

lower end of which is adapted to engage the 7 upper side of the assembly elevator, an upwardly'extending portion extending over the rear portion of the elevator slide bar and terminating at a point adjacent the lower edge of the delivery slide bar, a cam member secured to said delivery slide bar and extending downwardly and over the upper end of the lever and adapted to shift the lower end of said lever out of engagement with said assembly elevator When said delivery slide' bar is in normal position; in the operation of 10 said typesetting machine.

In testimony whereof, I have hereunto set my hand at San Diego, California, this 6th 1 day of ()c tober,1926. V
